Choppy sound on T32G (PCAP included) - phuygens - 11-28-2015 05:43 PM
Dear,
A few months ago we've deployed several Yealink T32G's with one of our customers.
We have several intermittent audio issues.
This is the setup:
- 3CX phone system on site A, +/- 20 phones are located on the local LAN on site A.
- 3CX SBC is deployed on site B, +/- 20 phones are located on the local LAN on site B.
- The choppy sound is on all the phones, but intermittent (at both locations), internal & external calls...
There is QoS implemented on the local LAN and on the 3CX SBC.
I've a PCAP attached on this post.
I've also a PCAP available (made this on de 3CX server) of a whole day (with around 70 phone calls in it, if you need this, I will make it available on dropbox or something like this).
The firmware of the phones is on 32.70.0.221 (last 3cx supported firmware).
The VAD, CNG & echo cancellation is enabled.
The jitter buffer is as default: adaptive, min 0, max 300, normal 120.
Should I change this to fixed 120,120,120?
Thanks for support!
Kind Regards,
Pieter

Hello Phuygens
I noticed from the pcap that you are using the G722 codec. I had an issue where when a T23G was calling a conference the audio was choppy. I change the phone to use PCMA (aLaw) codec and the problem went away.
I hope this is of some help.
